Treatment results
All initial treatment objectives were achieved with a well-aligned
dentition, closure of all the diastemas, good occlusion, and improved
facial aesthetics.
The whole treatment was achieved by retraction of both upper and lower
lips, resulting in a passive lip seal and relatively straight profile
after treatment. Good root parallelism was achieved with minimal root
resorption. There was an improvement in the incisor inclination and soft
tissue profile, particularly across the E-line and the nasolabial angle
(Igure 4c, 4d).
